The flywheel is the compressor pump’s pulley, which the belt attaches to and drives the crankshaft. Be sure the flywheel and motor/engine pulley is aligned, as a misaligned pulley and flywheel can damage the pump and motor/engine. Replace if cooling fins are missing. Most flywheels have a specific rotation (usually C.C.W. when looking directly at the flywheel) so be sure the flywheel is installed correctly when replacing it to efficiently cool the pump.
